Re: Best Printer for photo process ?

2011-12-31 by marc

HI 

Medical film printer i see was limited to 325DPI 

it use kind of thermal film so good process but lack of resolution ..



I just but a new xerox solid-ink "Wax"  printer 

1-) True 2400DPI resolution 

2-) ink was wax so it etch and for sure developer resist to 
    i see on this forum many user use very thin pcb on that printer
    for direct pcb printing whit good result 
    but my idea was use a exposed DIAZO film (microfiche)
    then develop it ,wax will serve as developer resist 
so result will be 2400 DPI diazo film  just like real pcb shop ;-)

3-) this printer use full length printing head so dot registration 
    was perfect ,it actually print image on rotating drum then
    transfer it to the paper ,this was made a quite low temperature
   (65DeG c) so this may not pose problem of film shrink

4-) it quite easy to transform it in all back printer by loading 
    Black ink block on all 4 tray ,so by manipulate the postscrip image it possible to have 4 wax dot think by pixel ,so in theory 3  time more opaque dark 

5-)if all above fail A4 size drum will make a perfect drum for  
   a DIY protoplotter ,since it well balanced ,have servo motor for drive it and knot it precise position 

will post result when i receive/test the printer 

if some one was interested this was in deep explanation of how this printer work , that reading tell me that it may make real nice artwork printer for pcb ..
